Acidic deposition arises when
A) VOCs mix with carbon dioxide in the atmosphere and fall to earth as rain or snow
B) carbon monoxide and sulfur dioxide combine to form acidic deposits
C) sulfur and nitrogen oxides mix with other particles and fall to earth as rain, snow, or fog
D) carbon dioxide and nitrogen oxides combine and reach the earth in precipitation

Question

Quizplus · Accepted Answer

Acidic deposition is the deposition of acidic or acid-forming pollutants from the atmosphere to the Earth's surface. This can happen when sulfur and nitrogen oxides mix with other particles in the atmosphere, such as water vapor or oxygen, and fall to the ground as acid rain, snow, or fog. Choice A is incorrect because VOCs (volatile organic compounds) do not directly contribute to acidic deposition. Choice B is incorrect because carbon monoxide does not contribute to the formation of acidic deposition, and sulfur dioxide alone does not lead to acidic deposition without the presence of nitrogen oxides. Choice D is incorrect because carbon dioxide is not a significant contributor to the formation of acidic deposition.
